Development of the Next Generation Flexible Tooling System

Larry Kirby, Ronald Weddle
Published 2019-03-19 by SAE International in United States
Flexible Tooling Systems have been developed as a reconfigurable part support system to enable trimming of multiple part geometries utilizing a single router or waterjet. The driver for this development has been improved part quality, elimination of ergonomic issues associated with manually trimming, and the elimination of cost for part number specific hard tooling and the associated cost for manufacturing, maintenance, and storage. This paper will briefly trace the evolution of aerospace parts trimming history. The remainder of the report will focus on the technical objectives associated with the development of the Next Generation Flexible Tooling System, how they were achieved including the process for validation of each support location in aircraft coordinates. This system is designed to increase part holding accuracy with specific support location validation, and significantly reduce system maintenance costs in wet or dry environments.

Automated Surface Preparation of Embraer’s Commercial Jet Fuselage for Painting Process

Embraer-Rogerio Scafutto Scotton
Encore Automation-Karl Schuknecht
Published 2019-03-19 by SAE International in United States
The surface preparation of the fuselage prior to painting is largely done manually in the Aerospace Industry; utilizing scrubbers, sanders, chemicals, and manlifts resulting in safety and ergonomic issues without delivering a consistent result. The automation of the process employing robots, vision systems, machine movers, and automated process equipment provided the following benefits: Improved Safety and ErgonomicsReduced exposure to hazardous materials and working conditionsImproved Consistency and QualityImproved Production Capabilities and Reduced Labor CostsReduced Material UsageLess weightLower environmental risksLower costThis paper will describe the equipment used and the process changes required to automate the surface preparation process, then discuss the benefits that were realized.

Touch Interactive Display Systems: Human Factors Considerations, System Design and Performance Guidelines

G-10TDS Touch Interactive Display Systems Committee
  • Aerospace Standard
  • ARP60494
  • Current
Published 2019-02-06 by SAE International in United States
This Aerospace Recommended Practice (ARP) addresses direct touch interactive electronic display systems installed in the cockpit/flight deck for use by pilots. Direct touch refers to interactivity where the display screen is the input surface. This entire direct interactive electronic display system is referred to as the touch system throughout this document and covers those items related to direct interactive touch on display devices. In cases where only the display and touch device are being considered, this is referred to as the touch screen. The ARP covers system design guidelines as well as the considerations and recommendations for system performance and human factors. This ARP is intended to cover systems installed in 14 CFR Part 23, 25, 27, and 29 aircraft. As an ARP this document collects what are considered good practices by developers, users, and regulators of touch systems. The state of touch technology and the application of that technology is still evolving. As a result, it is premature to develop quantitative guidance for some key touch characteristics. In addition to the recommendations, this document…

  • TBMG-33734
Published 2019-02-01 by Tech Briefs Media Group in United States

The wearable device product category is exploding in healthcare design. Wearing these sensory devices that continuously collect, measure and report the user's physiology, exercise behavior, lifestyle activity, and health status requires three key human factors in the design. In this two-part series on robotics and wearable devices, part 1 dives into wearable designs by taking a look at the research being done now that eliminates the device altogether.

 

Improved Clutch Pedal Ergonomic Position through Adjustable Clutch Pedal Assembly as per Anthropometry

Tata Technologies, Ltd.-Chandrakant Gopalrao Musale, Ashish Deshpande, Sachin Latare, Mangesh Deshmuk
Published 2019-01-09 by SAE International in United States
In automotive sector, worlds demanding more riding comfort so accelerator, brake and clutch pedals plays important roles in providing comfort or discomfort to driver. Now days automotive OEMs paying more attentions on providing comfortable ergonomics positions of pedals but it is difficult meet the requirement of each and every (all percentile populations) person because of packaging/manufacturing/costing constraint.Here we are providing the solution to meet the requirement of comfortable ergonomics position as per drivers wish for all kind of persons/drivers (5th percentile to 95th percentile) by providing the adjustable clutch pedal assembly with simple mechanism.Currently adjustment provided in driver’s seat to adjust the comfortable driving position which provide the comfortable positions for 25th percentile to 95th percentile peoples also this arrangement having some limitations such as space constraint in cabin also high belly with low height persons may face the issue of belly obstacle while steering the vehicles. To overcome these issues adjustment in the pedal is must for comfortable driving position.

Published 2019-01-09 by SAE International in United States
An automobile door is one vital commodity which has its role in vehicle’s function, strength, safety, dynamics and aesthetic parameters. The door system comprises of individual components and sub-assemblies such as door upper, bolster, armrest, door main panel, map-pocket, handle, speaker and tweeter grille. Among them, armrest is an integral part which provides function and also takes care of some safety parameter for the customers. The basic function of an armrest is to provide ergonomic relief to occupant for resting his hand. Along with this, it also facilitates occupant safety during a side impact collision by absorbing the energy and not imparting the reactive force on occupant. Thus an armrest has evolved as a feature of passive safety. The armrest design should be stiff enough to withstand required elbow load condition with-in the acceptable deflection criteria. On the other hand, armrest has to absorb the dynamic force by deflecting proportionally to the side impact load. In this study the various structure of armrest was analyzed to strike an ideal zone between functional and safety parameters.…

Ergonomics and Handheld Medical Devices: Five Vital Elements for Design Success

  • Magazine Article
  • TBMG-29108
Published 2018-06-01 by Tech Briefs Media Group in United States

Dexterity, precision, control and comfort — without them, no handheld or hand intensive medical device is a success, for either the medical professional using it or for the patient relying on the outcomes. Ergonomically driven design guides a successful device development process from concept through prototype to market. There are always five fundamentals required for world-class handheld instruments or hand-intensive devices.

 

Vehicle Ergonomics Analysis by Comparing Hand Reach Distances to Controls

Amity University Noida-Kashif Ali, Virat Kalra
Published 2018-04-03 by SAE International in United States
Vehicle Ergonomics can be simply defined as the ease and comfort with which the driver and occupants inside the passenger cell can access and use the vehicle controls or features. Ergonomics takes into consideration the ease of operating the vehicle and the comfort levels offered in terms of positioning of the controls and seating comfort as well. The research aimed to find statistically whether the controls and features inside the passenger compartment are within the anthropometric hand reach distance. The research was done by standardizing the driving position using SAE H-point standard document J4004 to fabricate an H-point tool to place each of the test cars seat according to standard dimensions. Therefore, the distances from both shoulder points of driver were taken into consideration. Moreover, the anthropometric data for 95th percentile human hand reach was used to test whether vehicle control parameters and features inside the passenger cell fall within the normal hand reach or not. The statistical data for 15 vehicles on sale in Indian market was then analyzed based on vehicle classes like…
